Clarification of Question by 42maru-ga on 24 Jun 2005 18:31 PDT

I am taking a supplement of bovine colostrum and recently tested
positive for a food allergy to whey and casein. I don't know whether I
need to discontinue the supplement or not since mine is a
delayed-reaction IgG food allergy.

Hi 42maru,

Yes, whey and casein are present in colostrum supplements. I found one
product that is casein-free, below.

Bovine Colostrum
http://www.greatvistachemicals.com/nutritional-supplements/bovine-colostrum.html
..."Supplemental colostrum is created by drying bovine colostrum and
is available in powder, capsules, tablets or chewable
lozenges......The greater part of this protein is comprised of whey
proteins. Immunoglobulins, mainly IgG, make up about 75% of the whey
proteins. Other substances found in bovine colostrum include casein,
lactoferrin, alpha-lactalbumin, beta-lactoglobulin, and the growth
factors insulin-like growth factor-1 (IGF-1), insulin-like growth
factor-2 (IGF-2), transforming growth factor beta (TGFbeta) and
epidermal growth factor (EGF). In addition, bovine colostrum contains
vitamins, minerals, lipids and lactose. Bovine colostrum may also
contain colostrinin, also known as proline-rich polypeptide (PRP), a
substance found in ovine (sheep) colostrum..."
